Nowadays, chemotherapy is still the main effective treatment for cancer. Herb prescriptions containing (also known as "Guang-Huo-Xiang") have been widely used in Chinese medicine today. In our research, we found that patchouli alcohol, a compound isolated from the oil of , exerted antitumor ability against human lung cancer A549 cells ability both and . MTT assay was used to assess cell viability. Hoechst 33342 staining and TUNEL cover glass staining provided the visual evidence of apoptosis. Caspase activity measurement showed that patchouli alcohol activated caspase 9 and caspase 3 of mitochondria-mediated apoptosis. Consistently, patchouli alcohol inhibited the xenograft tumor . Further investigation of the underlying molecular mechanism showed that MAPK and EGFR pathway might contribute to the antitumor effect of patchouli alcohol. Our study proved that patchouli alcohol might be able to serve as a novel antitumor compound in the clinical treatment of lung cancer.

Aims: Patchouli essential oil (PEO) is the major active ingredient of a famous medicinal plant Pogostemon cablin (Blanco) Benth. This study aims to investigate the anti-aging activities of PEO and its major component, and elucidate the underlying molecular mechanisms.
Main Methods: The anti-aging activities of PEO and its main component patchouli alcohol (PA) were investigated by examining the lifespan, senescence associated indicators as well as stress resistance of Caenorhabditis elegans.

Ethnopharmacological Relevance: Ulcerative colitis (UC), a chronic inflammatory bowel disease, has become a significant public health challenge due to the limited effectiveness of available therapies. Huoxiang Zhengqi (HXZQ), a well-established traditional Chinese formula, shows potential in managing UC, as suggested by clinical and pharmacological studies. However, the active components and mechanisms responsible for its effects remain unclear.

Article Synopsis
- Patchouli alcohol (PA) is a special ingredient used in traditional Chinese medicine that can help with gut health.
- A study found that PA can reduce inflammation in mice with ulcerative colitis (UC) by lowering levels of certain harmful substances in the body.
- PA changes the makeup of gut bacteria but doesn't affect its overall diversity, and it helps protect the gut by targeting specific pathways related to inflammation.

Article Synopsis
- Alzheimer's disease (AD) is a progressive brain disorder that affects memory, and the role of patchouli alcohol (PA) in treating it is not fully understood.
- This study used a mouse model of AD, induced by amyloid-beta (Aβ) and stimulated by lipopolysaccharide (LPS), to investigate PA's therapeutic effects on cognitive function and its mechanism in enhancing autophagy and reducing neuroinflammation.
- Findings showed that PA improved memory and cognitive impairments in mice and reduced microglial activation, likely by influencing the AMPK/mTOR signaling pathway to decrease neuroinflammation and enhance autophagy.
